Powershell : unable to add the members to collections - powershell

I face a problem in following test script.
I expect the following result as the output of it.
VM Name vCPU Memory
------- ---- ------
Server1 1
Server2 8
unfortunately, i am receiving the following output. Can someone help me to understand the mistake in the code?
enter code here
VM Name vCPU
------- ----
Server1 1
Server2
$obj_collection = #()
$report_data = New-Object System.Object
$report_data | Add-Member -MemberType NoteProperty -Name "VM Name" -Value "Server1"
$report_data | Add-Member -MemberType NoteProperty -Name "vCPU" -Value "1"
$obj_collection += $report_data
$report_data = New-Object System.Object
$report_data | Add-Member -MemberType NoteProperty -Name "VM Name" -Value "Server2"
$report_data | Add-Member -MemberType NoteProperty -Name "Memory" -Value "8"
$obj_collection += $report_data
$obj_collection


this? You need to add apple with apple because apple with potatoes can give strange behaviour
$obj_collection = #()
$report_data = New-Object System.Object
$report_data | Add-Member -MemberType NoteProperty -Name "VM Name" -Value "Server1"
$report_data | Add-Member -MemberType NoteProperty -Name "vCPU" -Value "1"
$report_data | Add-Member -MemberType NoteProperty -Name "Memory" -Value $null
$obj_collection += $report_data
$report_data = New-Object System.Object
$report_data | Add-Member -MemberType NoteProperty -Name "VM Name" -Value "Server2"
$report_data | Add-Member -MemberType NoteProperty -Name "vCPU" -Value $null
$report_data | Add-Member -MemberType NoteProperty -Name "Memory" -Value "8"

Questions about Powershell objects, property names, multiple property values with the same name and dot sourcing issues

There is code at the bottom of this to help make it easy to reproduce what I'm asking in my questions. My questions are:
$parentObject.Children.Children.Andrew."Birthday Info" --- is there a programmatic way to know to need quotes and add quotes?"
$parentObject.Children.Robert.Children.Peter."Favorite Foods" --- I understand it creates a property name conflict if I try to add "Name" with a different value more than once, how can I add "Name" with a different food value multiple times? Should it be an array that I keep adding to and replacing/updating?
$parentObject."01/01/1960". --- why can't I dot source the child properties
$parentObject.Children.Robert. --- why can't I dot source the child properties, the 3rd level seems to be the limit?
$parentObject.01/01/1960; --- fails, returns a "0"
$parentObject."01/01/1960"; --- returns property names "Location"
and "Years Together"
$parentObject.{01/01/1960}; --- returns
property names "Location" and "Years Together"
$parentObject."01/01/1960". --- does not dot source
$parentObject.{01/01/1960}. --- does not dot source
$parentObject."01/01/1960".Location; --- returns property value
"Hawaii"
$parentObject.{01/01/1960}.Location; --- returns property
value "Hawaii"
$parentObject."01/01/1960"."Years Together"; --- returns property value "72"
$parentObject.{01/01/1960}.{Years Together}; --- returns property value "72"
$parentObject.anniversary - 01/01/1960; --- fails, performs a math
equation
$parentObject."anniversary - 01/01/1960"; --- returns
property values "Hawaii" and "62"
$parentObject.{anniversary - 01/01/1960}; --- returns property values "Hawaii" and "62"
$parentObject."anniversary - 01/01/1960". --- does not dot source
$parentObject.{anniversary - 01/01/1960}. --- does not dot source

I think your elemental object should be a single person with the desired properties, including refences to child objects. Then define a marriage which references the individual people and stores the date & location.
Best to just avoid spaces in property names
Use tab completion to explore what's available through dot notation
FavFoods is created as an array by splitting a string that uses an arbitrary separator (+)
ScriptProperties are used to keep time-dependent values current
Play with the objects generated by this code:

Powershell object doesn't add member

For some reason when I wrote this Powershell object, the last member does not get displayed in my result:
$resultObject = New-Object -TypeName psobject
$resultObject | Add-Member -MemberType NoteProperty -Name Date -Value $date
$resultObject | Add-Member -MemberType NoteProperty -Name TotalPCs -Value $ad
$resultObject | Add-Member -MemberType NoteProperty -Name UnmanagedTotal -Value $total
$resultObject | Add-Member -MemberType NoteProperty -Name TotalEMEA -Value $adEMEA
$resultObject | Add-Member -MemberType NoteProperty -Name UnmanagedEMEA -Value $totalEMEA
$resultObject | Add-Member -MemberType NoteProperty -Name TotalAFRICA -Value $adAFRICA
$resultObject | Add-Member -MemberType NoteProperty -Name UnmanagedAFRICA -Value $totalAFRICA
$resultObject | Add-Member -MemberType NoteProperty -Name TotalAMERICAS -Value $adAMERICAS
$resultObject | Add-Member -MemberType NoteProperty -Name UnmanagedAMERICAS -Value $totalAMERICAS
$resultObject | Add-Member -MemberType NoteProperty -Name TotalAPAC -Value $adAPAC
$resultObject | Add-Member -MemberType NoteProperty -Name UnmanagedAPAC -Value $totalAPAC
$resultObject | ft -AutoSize | out-file -FilePath "C:\BAC\WSUSScripts\KPI\ManagedComputers.txt" -Append
I have no clue why since every info is retrieved the same way and for the other member it all works. The last member just falls off.

Powershell returns wrong output

I have simplified the process so that anyone can reproduce it (in my script it is a problem within a workflow, no functions involved, therefore I can`t save these values in variables and then show them by console). The first thing is to use powershell ISE.
function AAA {
$datum1 = New-Object -TypeName PSObject
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnB -Value "BB"
return $datum1
}
function BBB {
$datum2 = New-Object -TypeName PSObject
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnC -Value "CC"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnD -Value "DD"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnE -Value "EE"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnF -Value "FF"
return $datum2
}
AAA
BBB
Output:
ColumnA ColumnB
------- -------
AA BB
AA
Any idea why this happens?
EDIT:
I have solved this "sh1t" in the following way
function AAA {
$datum1 = New-Object -TypeName PSObject
$datum1 | Add-Member -MemberType NoteProperty -Name Index -Value "1"
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnB -Value "BB"
$datum1
}
function BBB {
$datum2 = New-Object -TypeName PSObject
$datum2 | Add-Member -MemberType NoteProperty -Name Index -Value "2"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnC -Value "CC"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnD -Value "DD"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnE -Value "EE"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnF -Value "FF"
$datum2
}
AAA |? {$_.Index -eq "1"} | FT
BBB |? {$_.Index -eq "2"} | FT
Anyway, can someone explain what's going on? I would really like to understand the reason and look for related information
EDIT2: Reply to Palle Due,
it doesn't work at all for my scenario as it adds a bit more complexity.
Out-Host is not an option. Example provided:
workflow Get-Report
{
param ([string[]]$computername)
foreach -Parallel ($computer in $computername) {
sequence {
InlineScript {
$AAA = Invoke-Command -ScriptBlock {
$datum1 = New-Object -TypeName PSObject
$datum1 | Add-Member -MemberType NoteProperty -Name Index -Value "1"
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnB -Value "BB"
return $datum1
}
$AAA | Out-Host
$BBB = Invoke-Command -ScriptBlock {
$datum2 = New-Object -TypeName PSObject
$datum2 | Add-Member -MemberType NoteProperty -Name Index -Value "2"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnC -Value "CC"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnD -Value "DD"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnE -Value "EE"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnF -Value "FF"
return $datum2
}
$BBB | Out-Host
} #endinlinescript
} #endsequence
} #endforeach
} #endWF
$results = #()
$results = Get-Report -Verbose -Computer "localhost","localhost"
$results | FT

The easy fix is to pipe the output to Out-Host:
function AAA {
$datum1 = New-Object -TypeName PSObject
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum1 | Add-Member -MemberType NoteProperty -Name ColumnB -Value "BB"
return $datum1
}
function BBB {
$datum2 = New-Object -TypeName PSObject
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnA -Value "AA"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnC -Value "CC"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnD -Value "DD"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnE -Value "EE"
$datum2 | Add-Member -MemberType NoteProperty -Name ColumnF -Value "FF"
return $datum2
}
AAA | Out-Host
BBB | Out-Host
gives the output:
ColumnA ColumnB
------- -------
AA BB
ColumnA : AA
ColumnC : CC
ColumnD : DD
ColumnE : EE
ColumnF : FF
The thing is that powershell likes to output custom objects with four members or less horizontally. With five or more members they are output vertically. And then some strange neatness priciple kicks in: If you output multiple objects in a row, powershell will try to keep the same format. So if you started out horizontally, it will keep going horizontally and only output members with the same name as the first custom object. If you start out vertically it will keep going vertically and output all names.
That's why if you go:
BBB
AAA
you will get
ColumnA : AA
ColumnC : CC
ColumnD : DD
ColumnE : EE
ColumnF : FF
ColumnA : AA
ColumnB : BB
instead.
I haven't been able to find any documentation for this. They're just my own observations.

PSObject with relational values - one to manny

want to populate the following PSObject so it can have a one:one or one:many relationship between IPs and hostnames.
$hostobj = New-Object PSOBject
$hostobj | Add-Member -MemberType NoteProperty -Name "ip_address" -Value ""
$hostobj | Add-Member -MemberType NoteProperty -Name "hostnames" -Value ""
This gives me the correct headings but when I try add more than one value, it will error one trying to add the repeat values:
$hostobj = New-Object PSOBject
$hostobj | Add-Member -MemberType NoteProperty -Name "ip_address" -Value "1.1.1.1"
$hostobj | Add-Member -MemberType NoteProperty -Name "hostnames" -Value "server1"
$hostobj | Add-Member -MemberType NoteProperty -Name "ip_address" -Value "2.2.2.2"
$hostobj | Add-Member -MemberType NoteProperty -Name "hostnames" -Value "server2"
Why is this?
Can do the one to many bit fairly easily:
$hostobj = New-Object PSOBject
$hostobj | Add-Member -MemberType NoteProperty -Name "ip_address" -Value "1.1.1.1"
$hostobj | Add-Member -MemberType NoteProperty -Name "hostnames" -Value "server1", "server2", "server3"
Either of these is the data set to extra from:
1.1.1.1 server1
2.2.2.2 server2
3.3.3.3 server3
4.5.6.7 server4 server5 server6 server7
8.8.8.8 server8
9.9.9.9 server9
1.1.1.1
server1
2.2.2.2
server2
3.3.3.3
server3
4.5.6.7
server4
server5
server6
server7
8.8.8.8
server8
9.9.9.9
server9

you want to create a list of objects like:
$ArrayList = New-Object System.Collections.ArrayList
$hostobj = New-Object PSOBject
$hostobj | Add-Member -MemberType NoteProperty -Name "ip_address" -Value "1.1.1.1"
$hostobj | Add-Member -MemberType NoteProperty -Name "hostnames" -Value "server1"
$ArrayList.Add($hostobj)
$hostobj = New-Object PSOBject
$hostobj | Add-Member -MemberType NoteProperty -Name "ip_address" -Value "2.2.2.2"
$hostobj | Add-Member -MemberType NoteProperty -Name "hostnames" -Value "server2"
$ArrayList.Add($hostobj)
so that $ArrayList contains all the host objects. and each object has one value for ip_address and hostnames.
If this does not help you please specify what you expect/what exactly you are trying to do/work with.

New-Object add-member - cannot add a member - powershell

I have a problem :(
I have many errors when I add New object with the same name of property which previously Object .
"Add-Member : Cannot add a member with the name "ServerName" because a
member with that name already exists. To overwrite the member anyway,
add the Force par ameter to your command."
it works but with errors;)
Have someone a solution for me ??
Below example code :
$OutputObj = #()
$OutputObj += New-Object -TypeName PSobject
$OutputObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server1"
$OutputObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$OutputObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01:20"
$OutputObj += New-Object -TypeName PSobject
$OutputObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server2"
$OutputObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$OutputObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01340"

You are adding the member on the array, not on the object. Try the following:
$OutputObj = #()
$NewObj = New-Object -TypeName PSobject
$NewObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server1"
$NewObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$NewObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01:20"
$OutputObj += $NewObj
$NewObj = New-Object -TypeName PSobject
$NewObj | Add-Member -MemberType NoteProperty -Name ServerName -Value "server2"
$NewObj | Add-Member -MemberType NoteProperty -Name Status -Value "online"
$NewObj | Add-Member -MemberType NoteProperty -Name Uptime -Value "01340"
$OutputObj += $NewObj
Alernatively, I would do the following:
$OutputObj = #()
$OutputObj += New-Object -TypeName PSobject -Property #{
ServerName = "server1"
Status = "Online"
Uptime = "01:20"
}
$OutputObj += New-Object -TypeName PSobject -Property #{
ServerName = "server2"
Status = "Online"
Uptime = "01340"
}
Since Add-Member destroys and generates a new object each time it is used.
